Books with title Trigonometry: Problem Solving using the Casio fx-991ES Calculator

This book has been written to enable you to gain a good understanding of trigonometry and how your Casio fx-991ES Plus calculator can be used to further your understanding of the subject. Trigonometry forms an important part of your A Level Maths syllabus and this book should be used alone side your classroom text book on the subject. It will provide you with the skills to perform trigonometry calculations on your fx-991ES Plus calculator. You will already have covered some of the material in this book in your GCSE Key Stages 4, in fact the first few chapters will consulate your existing knowledge.

If you have worked through Statistics Part 1 and Statistics Part 2 from Cambridge Paperbacks you will have gathered by nowthe subject of statistics requires a great deal of personal application in order to gain a good working knowledge of thesubject. Further Statistics builds on the knowledge you have already acquired. You will find that not all the subjects coveredin this book are included in the Statistics strand of your A Level Further Maths. That will depend on the examination boardsyllabus you are following. Many statistical techniques involve a methodology which is acquired with practice. An important part of the learning process is for you to work through each example using your own Casio fx-991ES Plus calculator. The results should be entered into your own note book – this is active learning and it’s only by doing this that you are likely to gain maximum benefit from the Cambridge Maths Method which underpins the whole learning process.

The second book on statistics in the Cambridge Paper-backs A Level Maths series contains much of the material you will need to continue on building your knowledge of the subject. Much of this book is given over to statistical methods and you will need a good understanding of them to gain a solid working knowledge of the subject. As with the first book, the Casio fx-991ES Plus calculator can play a significant role in furthering your understanding of statistics. You will be introduced to several of the in-built features the calculator has specifically for statistical calculations. You may have noticed by now, the major difference be-tween traditional maths and statistics that is the level of precision, the results of statistical processing are only approximations and not absolute values.

Matrices and Complex Numbers are crucial components of mathematics and a good understanding of how to use them is particularly important. This book, as the others in this series, is meant to work alongside your recommended text books you use in your A Level Mathematics. It acts as a supplement and will show you how the Casio fx-991ES Plus can be used to great effect in problem solving in both matrices and complex numbers. The fx-991ES Plus has features that are specifically designed to perform matrix calculations and complex numbers calculations. This book will show you how to use these features effectively.

Mechanics forms substantial part of your A Level Mathematics course and your Casio fx-991ES Plus calculator will prove invaluable as you gain an understanding and working knowledge of the subject. In this, the first of two books on mechanics, you will find many of the subject areas you are likely to encounter in the classroom. When your maths teacher introduces you to mechanics, as each new topic is started, look up the relevant chapter in this this book (or Book 2). Use it alongside the material your teacher covers and the material in your maths course book. You will find that many of the problems you are asked to work through are covered in this book and you will be able to use the same Casio fx-991ES Plus keystrokes to help you solve the problems.

Being good at algebra is an essential skill for anyone who uses mathematics. This is especially true if you are pursuing an A Level in maths. You can say algebra is the most fundamental maths skill. This book will give you the opportunity of enhancing your algebraic skills together with building your proficiency on the fx-991ES calculator.As expected, in every example the keystrokes for your calculator are given. It’s a really good idea for you to repeat the same keystrokes so to strengthen your understanding of algebra. In particular this book will convince you that your fx-991ES calculator should be a constant companion as you work on algebraic problems.Graphs are also included in many of the Examples as these will help in furthering your understanding and insight into functions and their behaviour.

Modelling is an important skill to acquire as it’s applicable to many areas of engineering and science. It is fair to say that today, there is no scientific discipline which would not benefit from the use of mathematical modelling.To get you started in developing a modelling mindset, you will be introduced to the principle of the Cambridge Maths Method which is,1. Here is the problem.2. Construct a mathematical model.3. Put numbers into your model.4. Here is the result, change the numbers to see new results.This method is applied to the many examples throughout this book; for example, a mathematical model is derived to give the volume or area of a composite structure – a shape or structure is made up of fundamental components with which you are already familiar.The importance of putting numbers into your model and seeing it produce results cannot be overemphasised. This is where the Casio fx-991ES Plus calculator proves to be an invaluable resource in your learning experience. It’s therefore important for you to work through each example using your own fx-991ES calculator so you are able to perform the calculations yourself.

Welcome to Part 2 of this series on calculus where the focus will be on integration. Proficiency in performing integration comes as a result of practice and this book has many exercises for you to work through. As in Part 1, you should use this book to compliment the work you are given in the class room. You will need to have worked through Part1 of this two part set on differentiation in order to understand a number of the techniques which are discussed in Part 2. You will discover how to use the power of your Casio fx-991ES Plus to work through many integration problems. You will find that it’s a real asset in furthering your understanding of calculus.

Mathematical modelling is a highly desirable skill to have as it has applications across all areas of science, engineering and technology. Traditionally it has been a difficult skill to acquire owing to the problems of implementation. However armed with the Casio fx-991ES Plus calculator, it is surprising how much can be learned and achieved with this modestly costing device. There was a time when only engineering was all about numbers; now life sciences, biology in particular, is now making mathematical demands on its graduates. In particular the modelling of biological systems and their behaviour. A good mathematical skill set is therefore essential for all scientists. This book has been written to help you develop a modelling mindset as you progress through your A Level Maths course. The task of being able to express a problem in terms of equations and then perform calculations can be achieved with relative ease when using a scientific calculator.

Calculus is an important part of A Level Mathematics and Part 1 of this two series focuses on differentiation, althoughChapter 10 is on Series and Series Expansions. It’s assumed you have already gained a very high grade in GCSE Maths andyou have good basic skills in algebra and trigonometry. The Casio calculator you are recommended to have in order tomake the most of this book is the fx-991 ES PLUS which is shown on the cover of the book.

Every student doing A Level maths or Further Maths will be expected to gain some knowledge of calculus and integrations in particular. The standard text books in the subject are adequate for satisfying the requirement of the syllabus. However, to gain a further understanding of integration it’s necessary to work through a varied range of examples. This book offers the reader the opportunity of doing just that. To perform integrations a good knowledge of the standard methods ofsubstitution and integration by parts is required and the examples in this book clearly demonstrate these methods.

This is the second book on mechanics in the Cambridge Paperbacks series on mechanics and as with the Part 1, this is best used together with your classroom text books on mechanics. Most of the topics you will cover in your classroom are discussed with special emphasis on how the the Casio fx-991ES PLUS calculator can be used to solve mechanics problems.
